This mod adds an item called "Calling Card". A calling card is something that is used to indicate the presence of something/someone.

NB: When I made this mod originally, it was for me only, and I therefore did not add a way of gaining the calling card via legitimate means. Therefore, to obtain the Calling Card, you must obtain it via Console Commands by doing the following:

1. Hit the tilde key to open the command console. The tilde key is left of the 1 key.
2. Enter into the console (Add quotes around Calling Card): Help "Calling Card" 0
3. With the Calling Card item being the only item which is displayed in the console, enter (where <ITEMID> is the item id, do not use triangular brackets):
player.additem <ITEMID>
